A charging control system includes a flattened charging speed calculation unit that calculates a flattened charge speed for fully charging EVs at a constant speed according to permitted charging time for the EVs and the amount of charging required by the EVs; a charging speed calculation unit that calculates a charging speed for the EVs by multiplying the flattened charging speed by a request demand ratio function based on change over time in electric power demand requested from the electric power supply side; and a control unit that controls the charging of the EVs on the basis of the charging speed calculated by the charging speed calculation unit.

Charging control system, charging control method, and program

A charging control system that controls charging of a plurality of vehicles that run on electricity includes: an assignment unit that assigns an order of priority relating to charging to the plurality of vehicles based on a predetermined index; a receiving unit that receives electric power demands that are requested from an electric power supply side; and a control unit that selects from among the plurality of vehicles in the order of highest priority charging-object vehicles in which the ON/OFF setting for turning charging ON and OFF is to be set to ON, and sets the ON/OFF setting of charging-object vehicles to the ON setting. The control unit changes the number of charging-object vehicles in response to changes in electric power demands over time.

Charging control system, charging control method, and recording medium

A charging control system that controls charging of an automobile that uses electric power as motive power include a receiving unit that receives electric power demands from an electric power supplier side; and a control unit that controls charging on and off of the automobile. The control unit changes a ratio of a charging-on duration and a charging-off duration in each duration in allowable charging durations for the automobile according to changes of the electric power demands over time.

A charging controller () controls charging of a battery by an interface device (-to-) on the basis of distribution system connection time when the interface device (-to-) and a battery mounted on EV (-to-) are connected to each other and on the basis of distribution system disconnection time when they are disconnected in each of the interface devices (-to-).
